To all whom t may concern.'

Be it known that I, JAMES P. BECKER, a citizen of the United States, and resident of'Miami, in'the county of Dade and State 5 of Florida, have invented certain new and useful Improvements in Closure perators, of which the following is a specification.

My invention relates to closure operators and has particular reference to improvements 1n devices forsecuring easement orv swinging window sashes in diEerent adljusted positions, my improvements consisting more particularly in the novel features of construction, combination and arrange- 16 ment' of parts as will be hereinafter more VAfully described, illustrated in the" accompanying drawings and defined in the appended claim.

- In the drawings, wherein like characters of reference denote corresponding parts in the different views.

Figure 1 is a horizontal section through a window showing a pair of my improved devices holding the swinging sashes of the window inj closed positions;

Fi re 2, an enlarged horizontal section showing in full and dotted lines, respectively a swinging window sash held in different adjusted'posltions by one of my improved devices.

Figure 3, alongitudinal section through the base portion and housing member of one of my devices; and

Figure 4, a detail view .showing the joint between the sections of the operating arm of one of my devices.

Referring. now Yto the drawings in detail, 10 designates a window frame including` a sill 11, and 12, 12, a pair of sashes hinged to the frame as at 13 for outward swinging movement. f

My improved devices for securing the sashes 12 in different adjusted positions are, in all essential respects', duplicates of' one'another, and therefore only one of them ywill be vdescribed in details It consists of a base plate 14, a housing 15 therefor, and a sectional operatingarm 16. Base .plate 14 is of elongated \rectangular shape and is ada ted, to be" secured to the window sill 1 1 y` means=of screws or other fasteners 17 as shown in Figure 2, while from the u per faeeof said p of and Ainidway betweenits side'edges, rises ate, near one end there- A a pin or lug 18, which -latter is threaded to receive a screw 19 for securing the housing.;u

15 over said plate.

Arm 16 extends across base plate 14 and through openings 20 and 21, respectively, formed in the side walls of housing 15, said arm, as aforementioned, being formed in two sections 22 and 23 pivotally connected together at adjacent ends asat 24 and each section having formed in one edge thereof one or more notches 25 to be selectively engaged with pin 18. A bracket 26 is secured to the sash 12 and the outer end of section 22 is pivotally connected to this bracket as at 27, while the inner or free end of section 23 is provided with a knob 28 or other suitable hand grip device for manipulatingl the A leaf spring 29 is mounted on the base plate 14 and exerts a pressure against arm 16 in the direction of pin or lug 18, so that when the arm is mampulated to engage a selected notch 25 withsaid pin or lu the arm is held thus engaged against acci ental release.

`I n the present instanceV the means for mounting leaf spring 29 on the base plate 14 consists of a series of staggered pins 30 rising from the base pla-te, the spring being woven between said pins, so that one end i thereof is disposed a ainst the edge of arm 16 opposite to the edge provided with the notches 25 and is free to flex to permit manipulation of Vsaid arm, while its other end abuts the inner faceof the adjacent end of the housing 15 by reason of which it is held against longitudinal movement from its effective relation with respect to arm 16.

The sections of arm 16 are of such length relative to one another `that pivot 24 is disposed inwardly of the housing 15 when the sash 12 is closed, whereby section 23 may be swung on said pivot to lie within the limits of the sill 11, the purpose being to .avoid an position shown in full lines in` Figure 1 and itl "desired to open the window, knob 28 is' grasped and section 23 is swung inward 'on pivot 24 slightly beyond a position of alinement with 'section-22,' section 22 at the same I time and by the same movement being swung to disengage its notch, 25 from pin 18. Arm 16 is then pushed outward until the sash 4has been opened tothe desired extent, when limit swinging movement of section 23 to4 a position slightly beyond alinement with section 22, thereby to produce a joint at 24 'that is broken in, the direction of the hinge 13 when the sash 12 is in the open position shown in Figure 2, so any tendency ofthe sash to .swing inward is positively prevented. Preferably Ian additional arcuate `slot-33 is formed 1n the slotted section of the arm, so that pin 31 may be engaged therein instead of in slot l32, so that whenthe window-'is closed the section 23 may be swung to an out of the way position towards the center Yof the sill 11, rather than towards an end ofthe sill, as in some instances it may be found that the window frame will interfere with swinging of said section 23 in the latter direction.

A. stop pin or lug 34 is providedon base 14 to limit swinging-movement of section 22 in the direction of spring 29 when. the section 23 is being swungl from -its full line position of Figure 1 to a positionin substantial alinement with section 22 prior to opening the window, thereby to avoid damage to spring29 and lat the same tilneprovide a rigid'surface' against which the arm 16 may operate .during its sliding movement to open or close the sash.

The pins 30 and 34 are, vdisposed to one side of a medial lineJextending longitudinally of the base plate, as is apparent from the showing intFigure 2 of "the drawings, and

. another 'set of pins 35 and 36, respectively,

corresponding to said pins 30 and 34, but

disposed to the other side of a medial line. extending longitudinally of the base plate,

is provided so that the leaf sprin may be reverse(1 and in the same p ate thus used with sashe-s that swingy open in either and the under face of the top of the ousing l 15, and ast/'ill be apparent from Fi re 2 of the drawings, insects are prevent y passingthrough the housing due to the leaf spring which is of the'sam'e height as 'the arm constantly bearing against one edge of the arm vand to the fact that the other edge of the arm contacts with one or the other of the adjacent edges of the side walls of the housingdefining the limits of'openings 20, 21, it being understood, of course that a screen covers` the window'openingas indicated by dotted lines at 37 in Figurel of the drawings and thatthe frame of the screen is notchedA where itl extends over the housing or housings 15, so that its lower edge may contact ywith the sill.

from

, From the foregoing description consid.`

`ered in connection with the accompanying drawings, it is believed that the construction, operation and advantages of my im? pproved device will be clearly understood.

It isl desired to point out, however, that va,l

rious changes and desirable additions may be made in and to the structure herein disclosed within the spirit-and scope of my in-1.

vention as dein/ed in the appended claim,

I claim v y t f A11 operator `for Swingin closures oomprising' an arm adapted to e pivotally secured at one end to a closure, a base plate adapted to rbe secured to a izzed support and gover which said arm is slidably disposed, ad pin, said meansproviding a stop cooperating with said arm to completely close saidl housing against-the passa e of insects.

In testimony whereof I ereunto aix my signature.
